How many cars are there on Nitro Type?

There are about 235 cars on Nitro Type.

And if you are wondering how I know that: type https://www.nitrotype.com/cars/9_small_1.png in the address bar. In place of 9 type a different number. 9 is the car ID. So if you put 1 in place of 9, it will show you the car with the ID 1. If you put 2, it will show you the car with ID 2; etc. It keeps going up to 225. As more cars get added to the game, 225 won't be the max number of cars there are.

But, Starting around March 2021, the newer cars no more have IDs. The cars with number IDs go up to ~ 225. The newer cars now have names. There have been more than 10 new cars added.
